Their distal ends are bent toward the center of the cap. The writer has found the number of chorial processes on an egg to range from 28 to 32. Whitmarsh (13),3 in his description of the stages of Nezara Jiilaris, states that there are as many as 65 of these processes on the egg of that species. The surface of the egg is rough- ened, with traces of hexagonal mark- ings.
